Who called from 4162140734

Recieved a call at 20:45. No message. Very suspicious. Could be the government

I got this call, it's from my friend
i think she called from a calling card

A European sounding woman asking to speak to the marketing company.  She did not know the name of our company or business.  They wanted to sell internet webhosting, searches etc.  Very persistant, but can't locate the company anywhere.   I listed the company below based on her suggested voice.
